Help very stuck

Expect to set up a system of two equations and two unknowns. Hint 1 A uniform 50-kg scaffold of length 7.0 m is supported by two light cables, as shown below. A 63-kg painter stands 1.0 m from the left end of the scaffold, and his paint bucket is 1.5 m from the right end. If the tension in the left cable is twice that in the right cable, find the tensions in the cables and the mass of the bucket. mbucket = kg Tleft = N Tright = N
